Flushing memstore could happen at any time and should not have visible performance impact.
Why you want to avoid doing that?

Subject: Whether turning off assignSeqIds using hbase bulk load will cause adverse impact
or not
Hi community:
Currently our environment will import about 200G into HBase each day.
These datas are cross six tables which table has about 100 Regions. We use HBase bulk tools
completed these import tasks. We investigate HBase source code found when bulk loading task
happen, HRegionServer will at firstly flush memstore according to each HRegion, We want to
turn off assignSeqIds avoid each HRegion to force flush memstore. But We don't know these
adverse impact if we do. Please help me to point out these impacts. Thanks
